According to SDxCentral, interest in a technology called Co-Packaged Optics (CPO) has grown over the past few years. It is reported that this technology provides higher power than traditional pluggable systems while saving costs.<\/span><\/p>\n

Although\u00a0the first co-packaged optical switches are expected to be launched later this year and chipmakers are investing billions of dollars to advance silicon photonics, we don’t expect them to be competitive very soon, according to Kevin Deierling, senior vice president of networking at Nvidia Corp.<\/span><\/p>\n

According to Kevin Deierling, engineers have had amazing success in delaying the commercialization of CPOs indefinitely. “I think the first time I heard about CPO was that when\u00a0we got to\u00a025Gb\/s<\/a> per link, we had to use onboard optics, then 50Gb\/s, and then 112Gb\/s.”<\/span><\/p>\n

Recently, Kevin Deierling’s team introduced a 51.2Tb\/s switch platform that has a 1U or 2U footprint, uses a 112Gb\/s serializer\/deserializer, and provides up to 64 800Gb\/s ports or 128 400Gb\/s<\/a> ports.<\/span><\/p>\n

“Somehow, all the different disciplines continue to make the traditional scheme work.” Kevin Deierling doesn’t think that’s going to change, at least not in the near future. “We can do a lot of really interesting engineering with chip connections without having to resort to esoteric onboard optics.”<\/span><\/p>\n
